Dixon assumes that Europe and Africa would eventually fuse, closing up the Mediterranean Sea. Asia and North America would collide and close up the Bering Strait. South America would split off from Central America. Australia would collide with southern Asia, uplifting a mountain range. Finally, parts of eastern Africa would split off to form a new island which he called Lemuria. Other volcanic islands have been added, such as the Pacaus Archipelago and Batavia.
